HUMIDIFIER.

Application led April 7,

' To allee/wm, t may concern.'

Be it known that I, WrLLrAM Boss, a citizen of the United States,residing at St. Paul. in the county of Ramsey and State of Minnesota,have invented certain new and useful Improvements in Humidfiers, ofwhich the following is a specification.-

My invention relates to humidifiers for use particularly in connectionwith steam radiators or hot wate` radiators, and an object is to provideeflicientmeans for keeping the air in the rooms containing the radiatorsin moist condition. Particular objects are to provide a humidifier|which may be conveniently and economically manufactured,

which may be readily installed in place upon a radiator, which willinsure rapid evaperation of water, and which will act to collect dustwhich is carried upwardly by the current of hot air rising from theVradiator.

The full objects and advantagesof my invention will appear in connectionwith the detailed description, and the novel features embodied in myinventive idea will be particularly pointed out in the claims.

In the accompanying drawings which illustrate one form in which myinvention may be embodied, Fig. 1 is a front elevational view of thehumidifier. Fig. 2 is a view of the humidifier in vertical longitudinalsection showing it inV place upon the top of a radiator. Fig. 3 is anend elevational view.

Fig. 4; is a view of the humidifier in verticalV transverse sectionshowing it in place on the top of a radiator. Fig- 5 is a view inhorizontal section on theline 5-5 of Fig. 4. Fig. 6 is a fragmentarysectional view of the fabric which I employ. Fig. 7 is a fragmentaryplan view of the fabric.

As shown in the drawings, I provide a casing 10, the front portion ofwhich is provided with a bottom 12 to constitute a water receptacle. Therear wall of this receptacle is constituted by a partition 14; which isspaced forwardly from the rear wall of the casing so as to provide avertical passageway 16 for the hot air rising from the ra- Y diator.V Aplurality of horizontal ro'dlike supports 18 extend .above the waterreceptacle from front to rear, these supports having end portions 2()which are bent downwardly at'right angles for Vsecuring 'the supports18, these end portions .being preferably soldered to the front and rearwalls of the 1922. serial No. 550,543.

casing 10. The fabric 22 having a width substantially the saine as thatof the water receptacle is folded back and forth over the supports 18 soas to have'portions extending down to the bottom of the water receptacleand other portions extending horizontally above the receptacle, theselower por tions and upper portions being connected by vertical portionsof the fabric as will be ap-l parent from Fig. 2. I provide a cover 2afor the casing 10, this cover having a periph eral depending flangeportion, the rear of which when the cover is in place forms an upwardcontinuation of the rear wall of vthr-r casing whereby a deflector isformed. The front portion and the forward side portions of theperipheral flange are provided with perforations or slots 2 6'as shownin Figs. 1 and3 for escape of the moistened air. The cover may besecurely held in place by horizontal supports 28, the end portions ofwhich are bent downwardly at right angles and soldered to the casing atthe two ends of the latter. The front portion of the water receptacle isprovided with a shield 30 within which is a fioat 32 to which is secureda vertical rod 34, the upper end of which is bent forwardly so as toextend through a slit 36 in the cover flange and is provided lwith ahead 38 upon observing which the amount of water in the receptacle isindicated.

The operation and advantages of my invention will now be apparent. Thehumidifier is placed on top of the radiator R so that the rear wall ofthe casing in connection with the rear flange of the cover constitutes adefiector which in use will engage the wall of the room or the windowledge L as shown in Fig. 4 and cause the hot air rising from theradiator to pass up through the passageway 16 and then'forwardly throughthe device from which it escapes through the Slots 26. The fabric whichI employ is preferably one having a pronounced nap as shown in Figs. 6and 7. Moisture is drawn up into the fabric by capillarity and isquickly picked up by the forwardly passing current of air impinging uponthe projecting nap. At the same time particles of dust carried by theair are retained. On account of the solid top portion of the cover, themoistened air is forced .to pass out into the room through the slots 26and the cover may be utilized as a support for various articles. Thewater receptacle'may be filled through any one ot the pertorations 26without removal of' the COVGI.

I claim:

1. A humidifier comprising a i casing adapted to rest upon the top of aradiator, arwater receptacle constituted by the'torward portion of saidcasing, the rear wall ot said casing` being` substantially parallel toand o t thesaine height as the rear wall ot said water receptaclewhereby a vertical passageway 1s formed for heated air from theradiator, a plurality ot rods having horlzontal portions extending abovesaid water 4 receptacle between the front and rear thereof forsupporting. a fabric with portions thereof extending down into saidwater re` ceptacle andA having` downwardly bent endsV Ywater receptacleconstitutec't by the forward yportion of said casing, the rear wall otsaid casing being substantially parallel to and ofthe same height asrtherear wall of said water receptacle whereby a vertical passageway isformed for heated air from the radiatorya plurality o rods havinghorizontal portions extending above said water receptacle between thefront and rear thereof for supporting a fabric with portionsthereofextending down intorsald water receptacle and having downwardlybent ends secured to said casing, a cover V'for said casing orcausingtheheated, air passing through said pas# l s ageway to i'rnpinge uponsaid fabric, said cover having peripheral dependingA front, rear'and endflanged: portions, the rear flanged portion forming an upwardcontinuation of the rear wall of said casing, and the front hangedportion and enda'langed portions being provided with perforar-tions forthe escape of moistened air, and two rods at the .ends ofsaid-casinghavingV horizontal portions located above saidfirst-nientioned horizontal portions and havingdownwardly bent endssecured to said casing whereby a support for said cover is formed.

In testimony whereof I hereunto aiiix my signature.
